(1) Only Japanese. (2) Intrusive and pointless login. (3) Network problems. (4) GPS problems and bad searching. Basically a nuisance app. Not a positive point that its main "virtue" is minimizing customer interaction with the McJob people. It makes me feel like the McJobbies already have a bad enough job without this app making it worse. I didn't give it one star only because it doesn't sink to that one-star level of terribleness. (The new registration almost got me to uninstall it. I absolutely do NOT want a more personal relationship with McDonald's.)

not a great app, not a great company This app keeps stopping when the phone language setting is English. I sent some inquiries to McDonald's about this issue, but they never responded. Poor customer service...

Requires use of email app I use the Outlook app, but cannot login without setting up a different email app. I do not want to setup a specific app just to log into another. This app used to be easy. I removed it from my phone and found that I go to McDonald's less often as a result.
